Rihanna and Chris Brown Back Together: Ashton Thinks RiRi Tipped Off Paps About Midnight Hook-Up!

Dag Ashton – we know you're pissed, but would Rihanna really have tipped off the paps? (Then again, this is the same girl who said that news leaking about her beating at the hands of Chris Brown was my liberation, my moment of bring it.)

Word on the street (okay, actually the print edition of OK! magazine) is that Ashton Kutcher is making Rihanna pay for their midnight hookup being caught on camera by paparazzi by breaking it off with her.

As soon as the news broke, OK! wrote, he called her and told her it was over, saying, 'I can't trust you.'

A little harsh, but okay – fair enough.

It looks like Ashton specifically told Rihanna to be ok the look out for paps, so I guess we can kinda get why he's mad. He was very specific that she check to make sure she wasn't being followed, OK! wrote. The way he sees it, she either screwed up or – even worse – tipped the photographers off herself.

Rihanna bristled at the accusation. Or, as OK! put it, she was super-offended.

She went off on him and told him she suspected him of calling the press. The way she sees it, he has more to gain from the fling than she does.

The source continued, in the way only a gossip rag source can: He's struggling with a terrible rep in Hollywood, and his brazen level of insensitivity toward Demi has only made it worse. Oooh, snap! He got a stern warning from his Two and a Half Men bosses, who don't want another Charlie Sheen on their hands.

Sounds a bit overdramatic, but then again, this is Rihanna we're talking about!
